the Rhone river to reach Monthey and Champery. In 2010 the railway took a step towards a unified brand image with the introduction of a two - tone green livery for its units. Line lengths and voltages Passengers carried: In 2007 TPC carried 2.1 million passengers, producing 14.5 million passenger-km. In 2008, after opening of the new narrow-gauge platforms in Aigle and the new depot, it was decided to change the voltage on the AOMC line from 900 to 1500 V DC. Some AOMC trainsets were adapted while older ones will be retired. Some AL and ASD trainsets reach the new depot trackage under reduced power. BVB: 17 km narrow gauge (1000 mm), electrified at 650 VDC. AOMC: 23 km narrow gauge (1000 mm), electrified at 850 VDC. AL and ASD: 6.2 km and 23 km narrow gauge (1000 mm), electrified at 1500 VAC.
